In this paper, a study was conducted to predict natural disasters in Afghanistan based on machine learning. Natural disasters need to be prepared not only in Korea but also in other vulnerable countries. Every year in Afghanistan, natural disasters(snow, earthquake, drought, flood) cause property and casualties. We decided to conduct research on this phenomenon because we thought that the damage would be small if we were to prepare for it. The Azure Machine Learning Studio used in the study has the advantage of being more visible and easier to use than other Machine Learning tools. Decision Forest is a model for classifying into decision tree types. Decision forest enables intuitive analysis as a model that is easy to analyze results and presents key variables and separation criteria. Also, since it is a nonparametric model, it is free to assume (normality, independence, equal dispersion) required by the statistical model. Finally, linear/non-linear relationships can be searched considering interactions between variables. Therefore, the study used decision forest. The study found that overall accuracy was 89 percent and average accuracy was 97 percent. Although the results of the experiment showed a little high accuracy, items with low natural disaster frequency were less accurate due to lack of learning. By learning and complementing more data, overall accuracy can be improved, and damage can be reduced by predicting natural disasters.

We evaluated the problems of the current disaster psychological recovery support system of the Ministry of Interior and Safety for periodic infectious disease disasters, including COVID-19 (coronavirus disease 2019). The current disaster psychological recovery support systems are challenging to preemptively respond to infectious disease disasters over a wide range and for a long period. These result from the workforce shortage according to the face-to-face consultation method and the limited real-time application of consultation contents. Additionally, due to the workforce shortage, it is difficult to track those who have experienced disasters in the long term. Furthermore, most disaster psychology evaluation tools are for adults, and there are few evaluation tools for children and adolescents. This paper presents an advanced disaster psychological recovery support platform technology that can actively assist people in psychological recovery from disasters while mitigating these issues.

A total of 594 reservoirs (17%), which are managed by KRC, equipped with earthquake-resistant facilities whereas remaining ones did not. In addition, reservoirs were placed without the effect of geological structures (i.e., fault and lineament). Therefore, development on technique for alleviating the potential hazards by natural disasters along faults and lineaments has required. In addition, an effective reinforcement guideline related to the geological vulnerabilities around reservoirs has required. The final goal of this study is to suggest the effective maintenance for the safety of earth fill dams. A radius 2 km, based on the center of the reservoir in the study area was set as the range of vulnerability impacts of each reservoir. Seismic design, precise safety diagnosis, seismic influence and geological structure were analyzed for the influence range of each reservoir. To classify the vulnerability of geological disasters according to the fault distribution around the reservoir, evaluation index of seismic performance, precise safety diagnosis, seismic influence and geological structure were also developed for each reservoir, which were a component of the vulnerability assessment of geological disasters. As a result, the reservoir with the highest vulnerability to geological disasters in the pilot district was analyzed as Kidong reservoir with an evaluation index of 0.364. Within the radius of 100km from the epicenter of the Pohang earthquake, the number of agricultural infrastructure facilities subject to urgent inspections were 1,180 including reservoirs, pumping stations and intakes. Four reservoirs were directly damaged by earthquake among 724 agricultural reservoirs. As a result of the precise inspection and electrical resistivity survey of the reservoir after the earthquake, it was reported that cracks on the crest of reservoirs were not a cause of concern. However, we are constantly monitoring the safety of agricultural facilities by Pohang aftershocks.

This study aims to find out a state of the damages and vulnerable areas from natural disasters in the Korean peninsula using the prevention meteorological database information made by Park(2007b). Through the correlation analysis between damage elements and total property losses, we investigate the damages of public facilities, which have high correlation coefficient, and the cause of disasters and want to propose the basic information to set up the disaster prevention measures in advance. As a result, because most of the total property losses is the damages of public facilities, we can reduce the damages of natural disasters if we can predict the damages of public facilities or carry out the prevention activities in advance. The most vulnerable area for the natural disasters are Cangwon-do and Gyeongsangnam-do provinces. The vulnerable areas for the damages of public facilities by typhoon are Daegu metropolitan city, Cangwon-do, and Gyeongsangbuk-do provinces. These vulnerable areas will take place more frequently due to the climate change including Gyeongsangnam-do province so that we need to set up the disaster prevention measures and natural disaster mitigation plan. Also, we think that it has effect on reducing the damages of natural disasters to predict the damage scale and strongly perform the prevention activities in advance according to typhoon track and intensity.

Objectives: This study investigated the socio-demographic characteristics and medical causes of death among meteorological disaster casualties and compared them with deaths from all causes. Methods: Based on the death data provided by the National Statistical Office from 2000 to 2011, the authors analyzed the gender, age, and region of 709 casualties whose external causes were recorded as natural events (X330-X389). Exact matching was applied to compare between deaths from meteorological disasters and all deaths. Results: The total number of deaths for last 12 years was 2 728 505. After exact matching, 642 casualties of meteorological disasters were matched to 6815 all-cause deaths, which were defined as general deaths. The mean age of the meteorological disaster casualties was 51.56, which was lower than that of the general deaths by 17.02 (p<0.001). As for the gender ratio, 62.34% of the meteorological event casualties were male. While 54.09% of the matched all-cause deaths occurred at a medical institution, only 7.6% of casualties from meteorological events did. As for occupation, the rate of those working in agriculture, forestry, and fishery jobs was twice as high in the casualties from meteorological disasters as that in the general deaths (p<0.001). Meteorological disaster-related injuries like drowning were more prevalent in the casualties of meteorological events (57.48%). The rate of amputation and crushing injury in deaths from meteorological disasters was three times as high as in the general deaths Conclusions: The new information gained on the particular characteristics contributing to casualties from meteorological events will be useful for developing prevention policies.

Across the world, the industrialization has increased the frequency of climate anomaly. The size of damage due to recent natural disasters is growing large and fast, and the human damage and economic loss due to disasters are consistently increasing. Urbanization has a structure vulnerable to natural disasters. Therefore, in order to reduce damage from natural disasters, both hardware and software approaches should be utilized. Currently, however, the development of a statistical access process for 'analysis of disaster occurrence factor' and 'prediction of damage costs' for disaster prevention and overall disaster management is inadequate. In case of local governments, overall disaster management system is not established, or even if it is established, unscientific classification system and management lead to low utility of natural statistics of disaster year book. Therefore, in order to minimize disaster damage and for rational disaster management, the disaster damage survey process should be improved. This study selected gale as the focused analysis target among natural disasters recorded in disaster year book such as storm, torrential rain, gale, high seas, and heavy snow, and analyzed disaster survey process. Based on disaster year book, the gale damage size was analyzed and the issues occurring from the correlation of gale and damage amount were examined, so as to suggest an improvement plan for reliable natural disaster information collection and systematic natural disaster damage survey.

Purpose: This study analyzed the relationship between working hours and the occurrence of industrial disasters based on manufacturing businesses that are members of Federation of Korean Trade Unions.Methods: Repliers were managers of the safety & health department in the union, and 215 surveys out of 300 businesses that agreed to participate in the research were analyzed. Results: 94 out of 300 companies, which counted for 43.7%, replied to have experienced industrial disasters. 56 of those (59.6%) had less than 52 working hours per week, and 38 companies (40.4%) had more than 52 working hours per week. 109 companies, which counted for 50.7%, did not have an incident of industrial disaster. Companies with an average of more than 52 hours of working hours per week were shown to have a 2.29 times (95% CI 1.08~4.87) higher possibility of having industrial disasters than those with less than 52 hours of working hours. Conclusion: As the study showed that industrial disasters were more likely to occur in businesses with working hours longer than 52 hours, ways to reduce working hours need to be developed and various safety measures need to be taken to prevent industrial disasters in case workers are undergoing long working hours.

과도한 인구의 밀집과 도시 하부구조시설의 집중이 될수록, 재난의 가능성은 그 만큼 존재하게 된다. 대부분의 도시가 예상치 못하는 자연적 및 인위적 재난을 대처 하는 데에는 많은 어려움을 지니고 있다. 많은 사례가 이미 증명되고 있듯이, 이러한 재난은 사회경제적, 재정적, 물질적 및 인명손실에 많은 영향을 초래하고 있다. 비록 여러가지 재난방지 프로그램을 준비해 왔지만, 재난방지를 위한 첨단경고 시스템을 구축하는데 있어서 부족한 점이 있다. 이 연구에서는 전화에 연결될 수 있는 자동음성통보시스템의 개념적 생각과 모델을 제시하고자 한다. 본 논문에서 제안한 개념적 모델과 시스템 구조는 재난을 예측하고 분석할 뿐만 아니라, 재난의 위험과 위기에 대한 해결책과 대책을 제시한다. 그러나, 지리적정보 측면에서 자동음성통보 시스템의 개념적 정의 및 모델에 대한 연구가 적은 듯하다. 따라서 이 연구는 자연적 재난과 인위적 재해를 조사하고 해결책을 제시하는 것을 강조하였다.
